1. A catheter sheath introducer for use in introducing a catheter into the body vessel and comprising:

  • a tubular housing having proximal and distal ends and having a passageway extending through said proximal and distal ends and the housing for slideably receiving an elongated catheter so that the catheter may pass through the housing from said proximal end to said distal end before introduction into a said body vessel;

    a tubular cannula extending from the distal end of said housing but not directly connected to said housing and adapted to be inserted into a said body vessel and being in communication with said passageway so that said catheter may slideably extend through the distal end of said housing and thence through said cannula and into a said body vessel;

    flexible coupling means connecting a first end of said cannula with said housing at the distal end thereof without any significant overlap between said first end and said housing and in such a manner that said cannula may be angularly displaced with respect to the distal end of said housing, without any bending of said cannula so that said cannula does not deform.
